The accuracy depends on the impedance being measured, the quality of calibration and degree of averaging. Typical accuracy for 6 standard loads at 36 points over the available frequency range is tabled below in polar impedance format, after factory calibration, with Averaging = 64 and 100% power output.

1 Ohm, magnitude +/-7%, angle +/- 3 degrees

10 Ohm, magnitude +/-1%, angle +/- 0.5 degrees

50 Ohm, magnitude +/-0.2%, angle +/- 0.2 degrees

1k Ohm, magnitude +/-2%, angle +/- 1 degrees

10k Ohm, magnitude +/-5%, angle +/- 2 degrees

100k Ohm, magnitude +/-7%, angle +/- 3 degrees

System Impedance Zo
(user defined)

User defined - must be a real positive number
(used to calculate VSWR, return loss and reflection coefficient)

Comes factory calibrated against 5 known loads, referenced to a HP8753D network analyzer with HP85032B Cal kit. The unit is supplied with a full calibration certificate.

Optional custom calibration can be performed using one of the available calibration kits (see optional accessories).

Cal files can be up or down loaded and saved to disc.
